Melon seedlings have just been unearthed and yellowed? Melons are stiff seedlings, what s going on w

The yellowing of melon seedlings when they are just unearthed may be caused by the following reasons:

1.Soil problems: Soil too acidic or too alkaline will cause the growth of melon seedlings to be hindered, and it needs to be adjusted according to the pH of the soil. Soils that are too acidic can be neutralized with lime or stone powder, and soils that are too alkaline can be conditioned with ammonium sulfate or magnesium sulfate.

2.Nutrient problems: Muskmelon has a high demand for nutrients, and a lack of nutrients such as nitrogen and iron will lead to stunted growth. Melons can be given an appropriate amount of nitrogen, iron and other fertilizers at the right time to provide sufficient nutrients.

3.Temperature and humidity problems: The growth of muskmelon needs the right temperature and humidity, too high or too low temperature and humidity will affect the growth of muskmelon. Proper adjustments need to be made in the greenhouse at the right time.

Causes and solutions for yellowing of melon leaves: The causes of yellow leaves caused by the first case are more complicated. Since the leaves are yellow, there must be a lack of chlorophyll, and the lack of chlorophyll is often caused by a lack of magnesium, nitrogen, potassium, iron, zinc and other elements, and it is difficult to figure out whether the deficiency of these elements is due to the climate, or the soil or root system.

In general, the main cause of mineral element deficiency is soil problems. Excessive use of chemical fertilizers causes secondary salinization of soil, which inhibits the absorption and utilization of medium and trace elements by crop roots. Therefore, in order to solve the problem of yellowing of the lower leaves of the melon, we should focus on dealing with soil salinization, and it is difficult to be effective by spraying foliar fertilizer several times.

The yellow leaves caused by the second situation are bacterial leaf spot disease, which is mainly caused by leaf friction and wounds, coupled with rainy and humid weather, which can easily cause spread and spread. It is recommended that streptomycin or neophytomycin or copper preparations be sprayed in the early stages of bacterial leaf blight. In the period of high incidence of the disease, it can be used to mix antibiotics appropriately.

The melon leaves yellow as soon as it is unearthed.

Summary. Hello, dear, it may be caused by low temperature in the shed.

1. It is necessary to spray Wufusheng in time to quickly restore the growth of the melon, and the effect of continuous spraying 2 times is better, and the temperature and ground temperature in the shed are increased at the same time.

Melons are stiff seedlings, what's going on with yellow seedlings?

Hello, dear, may be due to the low temperature in the shed caused by 1, need to be sprayed in time Wutan Ji Fusheng reverse damage Lianke quickly restore the growth of the melon, continuous spraying 2 times The effect is better, and at the same time, the temperature in the greenhouse and the ground temperature are high.

2.Hypothermia obstacles. The problem of stiff seedlings mainly occurs in the melon seedling stage, the growth of melon seedlings is more strict for the temperature requirements, at this time the melon requires the growth temperature is not less than 15 degrees (the ground temperature is not less than 11 degrees), lower than the above temperature, the melon new leaves, young leaves will be hindered, the crop stiff oak seedlings do not grow, and the melon root system is weak. Like a finch.

Summary. Good morning, dear. Dead seedlings and yellow seedlings of muskmelon are mainly caused by the high or low content of iron and zinc in the soil, which leads to the growth and development of crops. Some insect pests and pathogen infections may also lead to the emergence of yellow seedling phenomenon, such as root-knot nematode, cucumber chimeson virus, etc.

Melons are stiff seedlings, what's going on with yellow seedlings?

Good morning, dear. The yellow seedlings are mainly caused by the high content of iron and zinc in the soil or the low level of the over-sung section, which leads to the growth and development of crops. Some insect pests and pathogen infections may also lead to the emergence of yellow seedling phenomenon, such as root-knot nematode, cucumber incarcerated virus, etc.

Teacher: What is the disease of the dead seedlings of the melon withering.

Pro, the wilting of melon stiff seedlings is root-knot nematode, cucumber inlay disease, etc.

Hello, one of the reasons for a rough old fight is that the root system is weak. When the root system is weak, the growth is weak, and when the growth is weak, the leaves cannot be opened, and the growth point will be contained. The growth problem will further affect the fruit setting of the melon, even if you sit on the melon, when it comes to the expansion stage, there may still be that physiological wilting.

To put it bluntly, in the process of melon expansion, the leaves on the seedlings are drooping, especially at noon, the phenomenon of drooping leaves is the most serious, and some growers may think that it is a normal phenomenon and think that the melon is on the sugar, but in fact it is not. The most direct reason for leaf wilting is the lack of water, which will further lead to poor root system.

Hello, yellowing of the true leaf edges of melon seedlings is usually a sign of malnutrition, which may be due to a lack of nutrients in the soil, or the root system is not well developed. Here are some possible causes and how to deal with them:1

Nitrogen deficiency: Muskmelon is a fertilizer-loving nitrogen-loving plant. When there is a lack of nitrogen in the soil, the new leaf edges will show yellow nitrogen deficiency symptoms.

You can add nitrogen fertilizer to the roots or foliage. 2.Iron deficiency:

If there is a yellow iron deficiency on the edge of the true leaf, it may be that the iron content in the soil is insufficient, or the pH value is too high. You can solve this problem by adding iron-containing fertilizers to your roots or foliage. 3.

Magnesium deficiency: Magnesium deficiency in muskmelon seedlings can also lead to yellowing of leaves and the formation of spots. You can add anti-leakage magnesium fertilizer to the soil or spray magnesium-containing fertilizer.

4.Potassium deficiency: Potassium deficiency in melon seedlings can also lead to symptoms such as yellowing of leaves and edge death.

You can add a crack and potassium fertilizer to the roots. 5.Root Diseases:

Root diseases can also lead to yellowing of the true leaf edges, root rot, and poor root system development, so it is recommended to replace the soil in time, strengthen ventilation, and maintain the right temperature and humidity. When treatment, it is necessary to determine the specific cause before carrying out targeted treatment, which can be carried out such as nutrient supplementation, adjustment of soil conditions, and timely pruning of diseased leaves. At the same time, it is also necessary to maintain good ventilation and temperature, avoid the invasion of diseases and insect pests, and strengthen the management of melon seedlings to improve the survival rate and yield.

Summary. What is the reason why the growth point of melon seedlings is small, yellow, and hard:

1.Hypothermia obstacles. The problem of stiff seedlings mainly occurs in the seedling stage of muskmelon, the growth of melon seedlings is more strict for the temperature requirements, at this time the growth temperature of muskmelon is not less than 15 degrees (ground temperature is not less than 11 degrees), lower than the above temperature, the growth of new leaves and young leaves of muskmelon will be hindered, and the crop stiff seedlings do not grow, which has a lot to do with the weak root system of muskmelon.

2.Poor soil environment. Excessive water is contraindicated in the seedling stage in winter, and more water is not conducive to the absorption of nutrients in the root system. Excessive soil clay, poor soil permeability, and slow root growth are also important reasons for the "stiff seedlings" of muskmelon.

3.Destruction of the root system of the melon. Usually melon stubble, salinization, acidification, disease and other problems will destroy the root structure, and then lead to the "stiff seedling" chain effect, which occurs, but rarely.

Muskmelon "zombie seedling" solution:

1) For the phenomenon of "zombie seedlings" caused by low temperature, Xiao Wu recommends that once you find it, you need to spray Wufusheng in time to counter the damage.

Solution to the "zombie seedlings" of muskmelon: (1) For the phenomenon of "zombie seedlings" caused by low temperature, Xiao Wu recommends that once you find it, you need to spray Wufusheng in time to counter the damage.

1.Hypothermia obstacles. The problem of stiff seedlings mainly occurs in the seedling stage of muskmelon, the growth of melon seedlings is more strict for the temperature requirements of dust change, at this time the growth temperature of muskmelon is not less than 15 degrees (ground temperature is not less than 11 degrees), below the above temperature, the growth of new leaves and young leaves of muskmelon will be hindered, and the crop stiff seedlings do not grow, which has a lot to do with the weak root system of muskmelon.

2.Poor soil environment. In winter, the seedling stage is taboo to dissipate too much water, and the water is not conducive to the root system nutrient absorption, and the seedlings are watered once permeable, and the seedling is watered to drench the substrate to ensure the normal growth of the root system; Excessive soil clay, poor soil permeability, and slow root growth are also important reasons for the "stiff seedlings" of muskmelon.

There are more than a foot long, and the growth point is yellow and hard.

What about your region?

Huaihua, Hunan. That shouldn't be.

Then you can find the reason in the soil and the temperature.

Summary. Hello, melon transplanting right does not take root and wilts, is it when you transplant melon seedlings when the temperature is high, or when you water the root water, the temperature is high, the temperature is high so that the root tips of melon seedlings are damaged, so nutrients and water can not be transported, all wilting.

After transplanting, the melon seedlings do not take root and turn yellow, the leaves are hard, what is the reason for wilting?

Hello, melon transplanting right does not take root and fight the hall and debate the discussion, is it when you transplant the melon seedlings when the temperature is high, or when you water the root water, the temperature is high, the temperature is high so that the root tips of the melon seedlings are damaged, so the nutrients and water can not be transported, all wilting.

How to fix it. Pro-luck, as soon as possible to promote the root is the key to slow the seedlings, the root water should pay attention to the supplement of phosphorus and calcium, watering micro root force calcium + envy bending force, calcium and phosphorus, is conducive to promoting the root and seedlings quickly.

Summary. Hello, I am helping you to inquire about the relevant information and will reply to you immediately.

After transplanting, the melon seedlings do not take root and turn yellow, the leaves are hard, what is the reason for wilting?

Hello, I am helping you to inquire about the relevant information and will reply to you immediately.

Hello! The melon seedlings you transplanted may be covered with mulch, and now they are not rooting and wilting, is it that the temperature is high when you transplant the melon seedlings, or the temperature is high when you water the roots, and the high temperature damages the root tips of the melon seedlings, so the nutrients and water cannot be delivered, and all the wilting. It is recommended to pour some medicine to repair the root system, and do not water when the temperature is high!

Hope it helps!
